to internal combustion engines of the, inclined cylinder 'or V- type, and the principa rovide an engine in w alike in all particulars l object-thereof is to hich the two cylinder y locks present in theassembled engine arci 'so that only a single' ormof block has to be produced, as it may be used either` upon the right or uponthe left hand side of the engine. v

Other objects of my invention will appear' from the following connection with the disclosure of the preferred description which, in i drawings, constitutes a forni of my invention; it being appreciated, however, ythat my invention includes such variations 'and modifications of the particular embodiment thereof illustrated as c ome within the scope of the concluding claims. l

Referring now to the drawings, the crank case 1() of m improved internal combustion engine is o the type located inside andv up end thereof, which open by an oil pan Ii12 with which the lubricating' mechanism of the engine,

above 'I havingl bearings 11 not herein d'isclosed, is associated; and the open 'ends 'of said crank case are closedby cover plates which carry various accessory ower drive a motor vehicle, as is engine and of the gine is used to devices of the plant whenthe encontemplated herein; the front cover plate 13 serving as a support 14, the impellers of which are carrie 'shaft 15 supported in said cover p for two pum s 14,

inder blocks lof the case.

witha supply an ftherefor. bein shown in by the broken lineA e open 'lower' lower end is closed` pumps-14 may serial No. 497,957.

The crank case is provided adjacent the "cover plate 13 with a pedestal 16 which supports'a dynamo 17 at its upper end, and the shaft of'which carries, the fan 18; and the crank shaft, the cam shaft 20, the usual two-to-one gearing, and ily' wheel are of common and well known form in internal combustion engines..l The pump sha-ft is driven from the ,crank 4shaft through suitable'gears, as will`be understood;

The crank case 10 'is provided with two inclined surfaces Ior portions 26', 26 which serve as supports for the two cylinder blocks 27,127; said blocks being identical one with the other in every respect so that only one form of block has to be made, as any particular block may be placed either upon the right or left hand side thereof as the engine 'is b'uilt up and assembled upon the crank g These blocks Y are shown as arranged ninet degrees apart, although the plates 26 may eso inclined that the blocks stand at sixty degrees or at some other angle to one another, itpreferred.` The blocks are shown as having. tour cylinders each, although the number ot' cylinders may obviously be varied.

The several cylinders are provided each d an exhaust valve, the valves together `with the operating means Figure 2; and the cam shaft 20 is .provided with cams, one for one of each valve, that is siXteenin' all in ran engine n having two'four-cylinder blocks.

The-cylinder block is'providedwith an integral 1 longitudinally extending cooling liquid supply 'conduit 29 which is placed in communication at severaly points along' its length with the jacket space of the lock by lports .30; and this conduit is open at bothits' ends, as best shown 'in Figure.3, so Athat the discharge conduits 31 of the be connected of a supply, which side of the crank case a particular block is placed. In the assenibledengine `the yends of ,the conduits vremote 'from the pumps will be closed by plugs aswill bel appreciated. i

Inasmuch as but one` for1n 7of 'cylinder block is vemployed in an .engine itfollows with either end y conduit 29, dependent `upon that one form only of head is necessary the same bein urges 4y and 5 byl itselfil and A1n section in head 40 as the usual jacket shown inY JFig Figure 2;

space 32 which' This . Pumps rform is lin `communication with the cylinder block jacket space through suitable registering ports in the two, and from which space the conduits 33 lead back to theradiator as is usual in cooling systems. 'lihe jacket space 32 'Within the head is provided with two inlet ports with either one of which ay conduit 33 may communicate, as shown at 39 in Figure 4e; so that` heads identical in may be placed upon either side of the engine and the proper conduit rconnected with either end of the head; the port 39 not so used heilig closed by a plate, a screw or other plug, vor otherwise, the same as in' the case ot' the cylinder conduit' 29 above Y referred to.

The head is also provided with the usual priming` cock and spark plug opens ings which, however, are of connnon and well-known `form.

The cylinder block is provided with an inlet port 34 whichleads into an inl/et manifold 35, which is in-connnunication with the several inlet valves through suitable passages; and with exhaust ports V36 which lead into exhaust manifolds 37 sliown `in` Figure l only; the two exhaust manifolds in the complete engine being associated with a. heater Bton the combustible mixture supplied to the engine which, however, is not shown in detail, as'it forms no part ofthe invention to which @this present application relates.
